qcacld-3.0: Remove obsolete sap_start_work

Previously Policy Manager refactoring moved the logic for handling
different concurrency scenarios to the qca-wifi-host-cmn project.
Subsequently change I6cb9fe12bee3702556c9b52e7ccb7c69c762d8de
("qcacld-3.0: Remove legacy code for policy manager restructuring")
attempted to remove all of the legacy support. However a few remnants
remain, so remove the remaining support for the following items:
- sap_start_work
- is_sap_restart_required
- is_sta_connection_pending
- sap_update_info_lock
- sta_update_info_lock
